Also disclosed herein is a method of making 4-vinylbenzenepropanethiol. The method includes providing 1-bromo-3-phenylpropane, adding acetic anhydride and aluminum chloride, incubating the mixture at from about −20 to about 20 degrees Celsius for from about 1 hour to about 12 hours, isolating the resulting p-(3-bromopropyl)acetophenone, adding sodium borohydride to the p-(3-bromopropyl)acetophenone solution in methanol, incubating the mixture at about 0 degrees Celsius for about 2 hours, isolating the resulting p-(3-bromopropyl)-α-methylbenzenemethanol, adding toluensulfonic acid to the solution of p-(3-bromopropyl)-α-methylbenzenemethanol in toluene, refluxing the mixture under inert atmosphere for about 4 hours, isolating the resulting p-(3-Bromopropyl)styrene, adding thiourea to the p-(3-Bromopropyl)styrene, gently refluxing the mixture for about 16 hours, adding sodium hydroxide, and gently refluxing the mixture for about 4 hours.
